With the bicycle operating device 10, the rest position P0 is disposed between the first operated position P1 and the second operated position P2. The movable member 16 is configured to move the operation cable 2 in the pulling direction D11 to operate the bicycle component B2 in response to the first movement of the operating member 14 from the rest position P0 to the first operated position P1. The movable member 16 is configured to move the operation cable 2 in the pulling direction D11 to operate the bicycle component B2 in response to the second movement of the operating member 14 from the rest position P0 to the second operated position P2. Accordingly, it is possible to move the operation cable 2 in the pulling direction D11 even if the operating member 14 is operated in different ways.
Furthermore, the movable member 16 is configured such that the operation cable 2 is movable in the releasing direction D12 in response to the release of the operating member 14 from the first operated position P1. The movable member 16 is configured such that the operation cable 2 is movable in the releasing direction D12 in response to the release of the operating member 14 from the second operated position P2. Accordingly, it is possible to return the operation cable 2 to an initial position by releasing the operating member 14, allowing the structure of the bicycle operating device 10 to be simplified.

In the illustrated embodiment, the bicycle seatpost assembly 100 has a locked state, a first adjustable state and a second adjustable state. The bicycle seatpost assembly 100 has a structure configured to switch a state of the bicycle seatpost assembly 100 among the locked state, the first adjustable state and the second adjustable state using the bicycle operating device 10.
For example, in the locked state, the overall length of the bicycle seatpost assembly 100 is maintained at an adjusted overall length. In the locked state, the first cylinder 102 and the second cylinder 104 are fixedly positioned relative to each other in the telescopic direction D10.
In the first adjustable state, the overall length of the bicycle seatpost assembly 100 is adjustable to the first overall length L1 by just operating the operating member 14 of the bicycle operating device 10 to the first operated position P1. More specifically, in the first adjustable state, the second cylinder 104 stops relative to the first cylinder 102 at a position corresponding to the first overall length L1 when the second cylinder 104 downwardly moves relative to the first cylinder 102 from a position corresponding to the maximum overall length L0. In the first adjustable state, the first cylinder 102 and the second cylinder 104 are telescopically movable relative to each other between the maximum overall length L0 and the first overall length L1 in the telescopic direction D10.
Furthermore, in the first adjustable state, the overall length of the bicycle seatpost assembly 100 is continuously adjustable between the maximum overall length L0 and the first overall length L1 by operating the operating member 14 of the bicycle operating device 10 to the first operated position P1. In the second adjustable state, the first cylinder 102 and the second cylinder 104 are telescopically movable relative to each other between the maximum overall length L0 and the minimum overall length L3 in the telescopic direction D10. Namely, in the first adjustable state, a positional relationship between the first cylinder 102 and the second cylinder 104 is continuously adjustable within a first adjustable position range AR1. The first adjustable position range AR1 is defined between a first maximum overall length (the maximum overall length L0) and a first minimum overall length (the first overall length L1) of the bicycle seatpost assembly 100.
In the second adjustable state, the overall length of the bicycle seatpost assembly 100 is continuously adjustable within the adjustable range AR by operating the operating member 14 to the second operated position P2. Namely, in the second adjustable state, the positional relationship between the first cylinder 102 and the second cylinder 104 is continuously adjustable within a second adjustable position range AR2 (the adjustable range AR) different from the first adjustable position range AR1. The second adjustable position range AR2 is defined between a second maximum overall length (the maximum overall length L0) and a second minimum overall length (the minimum overall length L3) of the bicycle seatpost assembly 100. In the illustrated embodiment, the second overall length L2 shows possible overall lengths within the adjustable range AR while the first overall length L1 is a predetermined overall length.
As seen in
The first adjustable position range AR1 has a total length different from a total length of the second adjustable position range AR2. In the illustrated embodiment, the total length of the first adjustable position range AR1 is shorter than the total length of the second adjustable position range AR2. The first minimum overall length (first overall length L1) is different from the second minimum overall length (the minimum overall length L3). On the other hand, the first maximum overall length (the maximum overall length L0) is equal to the second maximum overall length (the maximum overall length L0). In the illustrated embodiment, the first minimum overall length (first overall length L1) is longer than the second minimum overall length (the minimum overall length L3).

The biasing force F21 presses the first contact part 280 to the second contact part 282. The biasing force F21 is transmitted from the movable member 226 to the operating member 214 via the first contact part 280 and the second contact part 282. The contact between the fifth contact part 288 and the sixth contact part 290 restricts the operating member 214 from pivoting relative to the base member 212 about the first pivot axis A51 from the rest position P50 toward the second operated position P52. This causes the operating member 214 and the movable member 226 to be positioned at the rest position P50 and the release position P60.

Therefore, in this embodiment, the operating device 210 does not include a positioning structure configured to position the movable member 226 at the first pulling position P61 and the second pulling position P62 relative to the base member 212 in a state where the operating force is not applied from the rider's finger(s) to the operating member 214. In the present application, possible examples of the phrase “release of the operating member” as used herein include moving the rider's finger(s) away from an operating member such as the operating member 214, and removing, from the operating member, an operating force applied from the rider's finger(s) to the operating member. In the embodiment, however, the operating device 210 includes a positioning structure which positions the movable member 226 only at the release position P60 in a state where the operating force is not applied from the rider's finger(s) to the operating member 214. In the embodiment, however, the operating device 210 includes a positioning structure which positions the movable member 226 only at the release position P60 in a state where the operating force is not applied from the rider's finger(s) to the operating member 214.
With the bicycle operating device 210, the rest position P50 is disposed between the first operated position P51 and the second operated position P52. The movable member 226 is configured to move the operation cable 2 in the pulling direction D51 to operate the bicycle component B2 in response to the first movement of the operating member 214 from the rest position P50 to the first operated position P51. The movable member 226 is configured to move the operation cable 2 in the pulling direction D51 to operate the bicycle component B2 in response to the second movement of the operating member 214 from the rest position P50 to the second operated position P52. Accordingly, it is possible to move the operation cable 2 in the pulling direction D51 even if the operating member 214 is operated in different ways.
Furthermore, the movable member 226 is configured such that the operation cable 2 is movable in the releasing direction D12 in response to the release of the operating member 214 from the first operated position P51. The movable member 226 is configured such that the operation cable 2 is movable in the releasing direction D12 in response to the release of the operating member 214 from the second operated position P52. Accordingly, it is possible to return the operation cable 2 to an initial position by releasing the operating member 214, allowing the structure of the bicycle operating device 210 to be simplified.

The bicycle operating device 210 further includes a take-up member 292, a positioning pawl 294, a winding pawl 296, and a control member 298. The take-up member 292 is rotatable relative to the base plate 224 about the rotational axis A6 between a first winding position P81 and a second winding position P82. The take-up member 292 is biased by a biasing element (not shown) to rotate relative to the base plate 224 about the rotational axis A6 in a first rotational direction D71. The control member 298 is rotatable relative to the base plate 224 and the take-up member 292 about the rotational axis A6. The control member 298 is biased by a biasing element (not shown) to rotate relative to the base plate 224 in the first rotational direction D71. The control member 298 is provided between the take-up member 292 and the base plate 224.
As seen in
The positioning pawl 294 is configured to selectively engage with the first protrusion 302 and the second protrusion 304 to position the take-up member 292 at the first winding position P81 and the second winding position P82. The winding pawl 296 is contactable with the third protrusion 306 to transmit a pivotal movement of the additional operating member 222 to the take-up member 292 via the third protrusion 306. The positioning pawl 294 is pivotably mounted on the base plate 224 of the base member 212 about a pivot axis A71. The positioning pawl 294 is biased by a biasing element (not shown) to pivot relative to the base plate 224 about the pivot axis A71 in a pivotal direction D81. The winding pawl 296 is pivotably mounted on the additional operating member 222 about a pivot axis A72. The winding pawl 296 is biased by a biasing element (not shown) to pivot relative to the additional operating member 222 about the pivot axis A72 in a pivotal direction D82. The winding pawl 296 is movable relative to the base member 212 in response to the pivotal movement of the additional operating member 222.
In
As seen in
The winding pawl 296 is disposed radially outward of the receiving portion 308 of the control member 298 in a state where the winding pawl 296 engages with the third protrusion 306. Thus, the winding pawl 296 presses the third protrusion 306 in the second rotational direction D72 without contacting the receiving portion 308.
The rotation of the take-up member 292 brings the second protrusion 304 into contact with the positioning pawl 294. Further rotation of the take-up member 292 moves the positioning pawl 294 away from the take-up member 292 via the second protrusion 304. When the additional operating member 222 is pivoted to the operated position P71, the second protrusion 304 passes through the positioning pawl 294 in the second rotational direction D72. When the additional operating member 222 is released by the user from the operated position P71, the take-up member 292 is rotated relative to the base plate 224 about the rotational axis A6 in the first rotational direction D71 by the biasing force of the biasing element (not shown). Thus, the positioning pawl 294 engages with the second protrusion 304 to position the take-up member 292 at the second winding position P82.
As seen in
The rotation of the control member 298 brings the release pawl 310 into contact with the positioning pawl 294. Further rotation of the control member 298 moves the positioning pawl 294 away from the take-up member 292 via the release pawl 310 so that the engagement between the positioning pawl 294 and the second protrusion 304 is released. Thus, the take-up member 292 is rotated relative to the base plate 224 in the first rotational direction D71 by the biasing force of the biasing element (not shown). At this time, the first protrusion 302 contacts the positioning pawl 294 to position the take-up member 292 at the first winding position P81 since the first protrusion 302 protrudes radially more outward than the second protrusion 304.
The control member 298 is rotated relative to the base plate 224 about the rotational axis A6 in the first rotational direction D71 by the biasing force of the biasing element (not shown) in response to the release of the additional operating member 222 from the operated position P71. Thus, the positioning pawl 294 engages with the first protrusion 302 to position the take-up member 292 at the first winding position P81. Accordingly, it is possible to switch a position of the inner wire 4b of the additional operation cable 4 between two positions corresponding to the first and second winding positions P81 and P82 by only operating the additional operating member 222 from the rest position P70 to the operated position P71.
The term “comprising” and its derivatives, as used herein, are intended to be open ended terms that specify the presence of the stated features, elements, components, groups, integers, and/or steps, but do not exclude the presence of other unstated features, elements, components, groups, integers and/or steps. This concept also applies to words of similar meaning, for example, the terms “have”, “include” and their derivatives.
The terms “member”, “section”, “portion”, “part” and “element” when used in the singular can have the dual meaning of a single part or a plurality of parts.
The ordinal numbers such as “first” and “second” recited in the present application are merely identifiers, but do not have any other meanings, for example, a particular order and the like. Moreover, for example, the term “first element” itself does not imply an existence of “second element”, and the term “second element” itself does not imply an existence of “first element.”
The term “pair of”, as used herein, can encompass the configuration in which the pair of elements have different shapes or structures from each other in addition to the configuration in which the pair of elements have the same shapes or structures as each other.
Finally, terms of degree such as “substantially”, “about” and “approximately” as used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed.
Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
